ok, patch attached.

Yes I know, I'm already using it. the problem is that I expect the
parser to recover after the wrong ENTITY declaration, in order to try to
catch more errors (if any), but with my fix it just prevents it from
doing that infinite loop, but does not help recovering. So since it
cannot recover it becomes so crooked that it reports a dozen error
messages which do not make any sense, since there was only one error.
Be warned that my patch just makes sure xerces finishes parsing with
reporting at least the ENTITY error correctly, the subsequent errors are
likely to make no sense at all.
